Heat pump repairs for Sandown homes
Whoever installed your heat pump, aftercare can be arranged in Sandown. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
We repair heat pumps in Sandown whoever installed them, including older monobloc and split systems. Across Sandown and the Isle of Wight, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
- Testing of sensors, pumps, valves, pressures and electrics
- Refrigerant repairs by an F-gas certified engineer where needed
Repairs in Sandown that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Sandown quote.

Short winter days in Sandown and what they mean
On the shortest day Sandown gets about 7 hours 58 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump repairs in Sandown: questions
How much does a visit cost in Sandown?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
Can you work on a heat pump in Sandown that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Sandown, whoever fitted them. Tell us the make and model when you get in touch.
What should I check before booking a visit in Sandown?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
Do refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
